315/25-kV Henri-Bourassa Substation

To meet increasing demand and ensure the long-term operability of its facilities, Hydro-Québec is implementing a plan for upgrading its transmission system in the northeastern part of the Montréal metropolitan region.

Construction of the new 315/25-kV Henri-Bourassa substation, which will replace the existing 120/12-kV Bourassa substation, falls under this plan. Located in the borough of Rivière-des-Prairies-Pointes-aux-Trembles, north of Boulevard Henri-Bourassa Est, near Boulevard Rodolphe-Forget, Bourassa substation is showing the effects of aging. Commissioned in 1955, most of its equipment is nearing the end of its service life and must be replaced. The preferred solution is to build a new 315/25-kV substation.

The project will have minimal environmental impact because it consists mainly of building a new substation on the same industrially zoned property as the existing substation, as well as adjusting the path of the nearby power lines.
